I was worried when I switched to a natural toothpaste from my old usual, Crest, but my teeth feel better than ever! I've noticed an increase in gum health as well and my breath just simply smells better. The texture takes some getting used to, and if you don't like tea tree, this isn't the product for you. But the subtle mint flavor makes it all the more pleasant for me. I get that "fresh, clean feeling" without all the toxic gunk that's in the stuff I used to brush with.
